.Tall whom t may concern:

,Be it known that l, ALBERT Lnrsnrg, a c1t1- America, `refabrics alone; and the invention consistsmore specifically of certain improvements in cement supplied to themachine for doubling fabrics, for which Letters Patents No. 1,042,129 were granted to me on October 22, 1912, so that the waterproof cement employed for uniting the two layers of fabric can be applied in a more eiective manner andthe construction of the machine rendered less complicated and moge efficient in use;`and for this purpose the-invention consists .of a machine for doubling fabrics in which the doctor by whichthe waterproof cement is applied to one of the fabrics to be doubled or united to the other fabric is combined with the abutments arranged at opposite endsof the heated pressing-.rollsfor the fabric and heated up while being applied to the fabric by a steamheating pipe located in close proximity to the doctor and the liquid waterproof cement; and the invention vconsists further of certain detai-ls of construction-which will be fully described hereinafter and finally pointed out inthe claims.

"in the accompanying drawings, Figure l represents a side-elevation of my improved machine for doubling fabrics, Fig. 2 is a vertical longitudinal section of the same, on

line 21-2, Fig. 3, Fig. 3 is a plan-view of the machine, Fig. 4 is a detail vertical transv verse section,`on line d fi, Fig. 3, through the doctor used for regulating the supply of liquid waterproof. cement to one of the fab- 'ries tc be united, said figure also showing the abutments for holding the waterproof the fabrics, Fig. 5 is a detail vertical section of the 'scraper used in connection with each one ofthe heated compression-cylinders for buildingnp or `interior steam-pipes 5.1

uniting the `two layers of fabric, and lFig. 6 isa detail .top-view of one end of the scraper, shown in lFig. 5, and one of its adjusting screws.

Similar letters of reference indicate corresponding parts #throughout the several figures of .the drawings.

Referring to the drawings, a, a are two hollow-rolls whichareflocated sidewise of es eachother in the supporting-frame f and which are heated by means of live steam ad mitted to the interior of the rolls by steam .supply-pipes that 'are connected with the rolls, the steam being carried ed by suitable exhaust-pipes b2 at the interior of the heating-pipes 1' fat the end of the supportingframe f. The heated roll a is supported in bearings of stationary standards of the supporting-frame 7, while the heated roll al. 1s supported in bearings of horizontally-ad'- justable slide-rests (Z1 which are guided on the frame je, so the roll al can be adjusted closeriormfarther away from the stationary 30 rollcsforproviding for the different thicknesses of the fabrics to be united. l:The adjustment of the movable roll. al is accomplished by means of screws Z2 having handwheels cl3, said screws acting on the slide rests of the roll ct. The rolls a, a1 are rotated at the same speed and in opposite direction to each other from a driving-shaft s which is supported in suitable bearings inthe side-standards of the rolls and by intermediate driving gear1 wheels' g, g1, respectively on the drivingshaft and a short'intermediate shaft, el supported in bearings of the side-standards f1 and gear-wheels g2 and respectively. rlhe two layers of fabric to be united are wound up on reels, Athe shafts of which are supported in bearings e, c1 at the opposite ends of the frame ,f and conducted over suitable guide-rolls c2 and c and adi0@ instable tension-rolls et, c5

The bearings apply a regulating tension to both layers of UC fabric.

*At the endsof the heated rolls a, a? are at one end of the 7o frame f below the v g3 on the rolls c, c1 95 Q they are united by the nesses of the located vertical abutments t, the lower ends of which extend by means of arc-shaped tapering lower portions h1 into contact with the roll a, the arc-shapedportions being arranged in close proximity tothe headsof the roll a. The abutments It are supported on downwardly-extending inclined recessed plates h2 which serve also for supporting an adj1 stable block z' that extends transversely from one side-standard f1 of the frame f to the other and to the face lof which is attached by means clined doctor l that is adapted to be adjusted closer or farther away from the heatof fastening-screws an inaccording to the different thickface-fabric to be doubled-up or the layer of cement to. be supplied to the backing fabric, by means of screws h5 having hand-wheels h6 at their upper ends, said screws being threaded in suitable keepers a attached to the inclined supporting-plates h2 and the' lower ends of which are swiveled into the upper ends of the guide-block z', as shown in-F` ig. l. he recessed abutments h are supported on the upper ends ofl the guide-block vl and rigidly attached thereto by means of clamping bolts 7a3 which are applied to the upper rear-ends of the abutments,l as shown in Fig. Ll.` The inclined supporting-plates h2 and the keepers h4 for the adjusting screws are firmly attached to thev upper part Vof the side-standards f1 of the supporting frame f. The abutments Zt', h1 and the doctor l form with the roller a, and the fabricthereon, a trough to hold the liquefied waterproof cement. The inclined screws h5 enable the doctor to be adjusted radially of the roller, thereby regulating the thickness of the layer of cement placed thereon, and enable adjustment for different thicknesses of fabric, and for wear of the edge of the doctor. The waterproof cement is supplied to the trough referred to in heated and liquefied condition and is kept in this condition so as to enter the pores of the fabric to be coated by means of a steamheated pipe 79 which is located in a longitudinal recess 2 at the lower end of the guideblock z' in close proximity to the lower portion of thedoctor. The live steam is supplied at one end to the supply pipe Q91 and conducted oli at the opposite end of the same through the pipe p2, as shown in Figs. 1 and 3. The cement is spread uniformly over the surface of the covering-fabric and is then lirmlyunitcd with thebacking fabric by the pressure exerted onboth the covering or, face-fabric andthe backing fabric by the heated pressure-rolls during the passage of said fabric between the same, the two layers after being doubled or united being then conducted olf by passing over the roller e6 on to the conveyer for drying.

Below the hea-ted rolls a, al

ed roll a,

below the heated rolls and in con-l tact with the lower circumference of the same, are arranged scrapers Z, Z1L which extend acrossthe full length of the rolls between the side-standards f1, said scrapers being heldinto close contact with the sur-- faceof the heating rolls so as to remove any traces of cement `that should be pressed through Athe minute openings or meshes of the fabric on to the surface of the same, or that portion of the cement that should run over the edges of the fabric passing over the roll a, so that the surface of the heated rolls is kept absolutely clear of e'ven the slightest traces ofcement and thereby the surfaces of the doubled-up fabric kept likewise perfectly clear of cement. The Scrapers Z, Zl are 'supported on transverse guide-blocks Z2 of rectangular cross-section that are supported in the upper portions of holders Z3 which have rectangularly-recessed lower portions Z4 that are bolted to the transverse bars, Z5 supported by the side-frame f'. lThe Scrapers Z1 are applied to guide-blocks Z2 and adjustedto the lower surface of the-heatingrolls a, al by set-screws Z6 having handwheels ZT at their lower ends,as shown clearly in Figs. 5 and 6. Y

For preventingthe bending of the scrapers Z, Z1 midway of their length and holding them in intimate contact with the ,heated rolls, auxiliary holders Z8 are arranged at one or more points intermediately of the length of the Scrapers, said auxiliary holders being likewise supported on the transverse bars Z2 and prevented from turning thereon owing to the rectangular shape of the bars and the corresponding recesses of the holders.

, The cement that is removed by the scrapers from the surface of the rolls is collectedk ina suitable receptacle (not shown) at the lower part of the frame below the Scrapers and returned `from time to time intothe trough-shaped space between the fabric on the heated roll a, abutments L and doctor e', `or it may be mixed with a new quantity of cement and-supplied therewith into the said troughshaped space, the doctor acting in the nature of a scraper for supplying the waterproof cement to the fabrics to be doubled-up or united.

Any suitable fabrics may be doubled-up by the machine, such as artificial leather and mohair, and a suitable backing fabric, said doubled-up fabric being used for upholstering purposes for the tops of automobiles, and for other purposes. The fabrics are doubled up by the heated rolls as a uniform pressure is exerted on the same as they are passed through the rolls and as the cement is supplied in a slightly-heated liquefied condition to the fabrics, they are uniformly doubled-up and at the same time dried to a considerable extent so that further artiiicial ydrying is not required. The properly located at opposite ends doubled fabrics are wound up on a suitable roller and ready and use,
